When the light comes on you probably have 50 miles left. It is best to always run with at least 1/4 to 1/2 at tank if you can. The pump in the tank has to transfer fuel from one side to the other and send it through the filter to the engine. I dont know if low fuel puts a strain on the pump or it picks up bits but the result can be the pump stops and you have fuel on the gauge but it wont go.
This usually happens at the worst moments. It happened on mine at 70mph on the outside lane of the A1 overtaking a truck.
